Abstract
Systems and methods for accelerated multi-contrast PROPELLER are disclosed herein. K-space is sampled in a rotating fashion using a plurality of radially directed blades around a center of k-space. A first subset of blades is acquired for a first contrast and a second subset of blades is acquired for a second contrasts. The first subset of blades is combined with high frequency components of the second subset of blades to produce an image of the first contrast. And the second subset of blades are combined with high frequency components of the first subset of blades to produce an image of the second contrast.
Claims22
A method for multi-contrast magnetic resonance imaging, the method comprising:
- sampling k-space in a rotating fashion using a plurality of radially directed blades around a center of k-space, wherein a first subset of blades is acquired for a first contrast and a second subset of blades are acquired for a second contrasts;
- combining the first subset of blades and high frequency components of the second subset of blades to produce an image of the first contrast;
- and
- combining the second subset of blades and high frequency components of the first subset of blades to produce an image of the second contrast.
A processing system for multi-contrast magnetic resonance imaging, the processing system comprises:
- a storage device storing instructions;
- and
- a processor coupled to the storage device and when executing the instructions, performing operations of:
- instructing a magnetic resonance imaging (MRI) scanner to sample k-space in a rotating fashion using a plurality of radially directed blades around a center of k-space, wherein a first subset of blades is acquired for a first contrast and a second subset of blades are acquired for a second contrasts;
- combining the first subset of blades and high frequency components of the second subset of blades to produce an image of the first contrast;
- and
- combining the second subset of blades and high frequency components of the first subset of blades to produce an image of the second contrast.
A method for multi-contrast magnetic resonance imaging, the method comprising:
- sampling k-space in a rotating fashion using a plurality of radially directed blades around a center of k-space, wherein the plurality of blades consists of a subset of blades acquired for a main contrast and at least two subsets of blades each acquired for a supporting contrast;
- and
- combining the subset of blades for the main contrast and high frequency components of the at least two subsets of blades for the supporting contrasts to produce an image of the main contrast.
